Light concrete precast compound roof board

Abstract

The invention relates to the technical field of building precast roof boards, and provides a light concrete precast compound roof board which comprises a waterproof reinforced layer and a heat insulation layer. The waterproof reinforced layer is arranged on the heat insulation layer, reinforcing meshes are arranged on the upper portion and the lower portion of the heat insulation layer, reinforcing ribs are arranged on the lower portion of the waterproof reinforced layer, and the waterproof reinforced layer, the heat insulation layer and the reinforcing meshes are cast into a whole through light concrete. Mounting parts connected with adjacent compound roof boards are arranged at two ends of the compound roof board, a decorative surface layer can be arranged on the waterproof reinforced layer, the mounting parts include upward opening grooved profiles or corresponding press strips, and the gap between the adjacent compound roof boards is sealed by the mounting parts and weather proofing sealants. The light concrete precast compound roof board has the advantages that the decorative surface layer, the waterproof reinforced layer, the heat insulation layer and the reinforcing meshes are integrated to form the compound roof board, the compound roof board is good in integrality, waterproof, resistant to aging, long in service life, high in strength, not easy to damage in transportation, high in construction efficiency and suitable for popularization and application, and ready-made secondary holes are decreased.

Description

technical field [0001] The invention relates to the technical field of building prefabricated roof panels, in particular to a lightweight concrete prefabricated composite roof panel. Background technique [0002] At present, there are mainly two types of prefabricated lightweight roof panels for traditional buildings: one is ALC roof panels: porous concrete forming panels (containing steel bars) made of fly ash, cement, lime, etc. mesh). Light in weight, good in thermal insulation and sound insulation, it can be used as a structural layer of roof panels, such as figure 1 shown. The other type is ASA roof panel: it is a kind of building roof panel made of fly ash as filler, cement as gelling agent, and alkali-resistant glass fiber mesh cloth or steel mesh as reinforcing material. Light weight, thermal insulation, sound insulation, fire resistance, can be used as roof panel structural layer, etc.; such as figure 2 shown. [0003] The above two types of lightweight prefab...
